Either the stock is very LQ or the whole sig is just plain blurry. Sharpen the stock and some of the effect layers (like the splatter and some of the color area's). Also, more color in the left area would be great. Especially at the gray-zones. As for text, I'd leave it textless.
lol @ random lower left orange spot. But yeah, what Darky said. Sharper. Ah ah... :\ Leaving it colorless would match the girl more. But I know nothing of matching. So disregard that if it's lame.
The BluRR...sharpen the **** out of it lawl. It'd look good. Change the border to 1px black. Looks sick with this type of sig. Sharpen more of your effects so it's more noticeable. And of course, the text can be different. Not bad man, still lookin' good. GJ.
